How Round Funded shows CAC before the raise

Most founders quote a CAC from a slide and hope nobody asks how it was built. Round Funded starts from spend and customers, not the deck.

You enter marketing spend, optional sales spend, and new customers for the same window. The CAC calculator divides that into blended CAC and marketing-only CAC, then shows payback against LTV so the number is not a blended vanity guess from three channels mashed together.

If paid is cheap and sales is expensive, you see both. Same inputs you already have in the ad accounts and Stripe. Output is the CAC you can say before the raise, not a rounded figure from last quarter.

That is the whole mechanic. Spend in, customers in, unit cost out.
